advertisement 3MHz Micropower Synchronous Boost Converters Deliver
3W from Two Cells in a Tiny MSOP Package
Design Note 246
Mark Jordan
Portable electronic devices operating from one or more
alkaline or nickel-metal-hydride cells require a boosted
supply that is both small and efп¬Ѓcient. Linear TechnologyвЂ™s new LTC В®3401 and LTC3402 are high frequency
micropower synchronous boost converters that operate from an input voltage below 1V and deliver up to
1A of output current from two cells. DC/DC efп¬Ѓciency
can be as high as 97%. The operating frequency,
output voltage and Burst Mode В® operation are all
user programmable, allowing these products to п¬Ѓt in
various applications where size considerations must
be balanced against efп¬Ѓciency. Furthermore, all of this
functionality is packed into a small, thermally enhanced
MSOP-10 package.
The LTC3401 is optimized for applications requiring less than 1.5W of total output power from two
alkaline cells, whereas the LTC3402 is optimized for
applications requiring 3W or less from two cells.
High efп¬Ѓciency is achieved through internal features
such as lossless current sensing, low gate charge,
low RDS(ON) synchronous power switches (0.16О©
NMOS, 0.18О© PMOS) and fast switching transitions …
